Eastern Time (ET)

UTC Offset: UTC -4

Eastern Time (ET) is a principal time zone in North America, observed across parts of the United States, Canada, and select regions of the Caribbean. It operates on Eastern Standard Time (EST) at UTC−5 during the fall and winter months, and transitions to Eastern Daylight Time (EDT) at UTC−4 during the spring and summer months, in accordance with daylight saving time practices. ET is followed in major metropolitan areas including New York, Washington D.C., Toronto, Atlanta, and Miami, making it one of the most influential time zones in the Western Hemisphere.

Importance and Global Use of Eastern Time

Eastern Time is one of the most influential time zones in North America, widely used for coordinating activities across government, business, media, and everyday life. It serves as the official time for major cities and institutions, including financial markets like the New York Stock Exchange and federal operations in Washington, D.C. Its alignment with key population and economic centers makes it a primary reference for national schedules and time-sensitive systems.

Due to its prominence, Eastern Time is commonly used as a standard in broadcasting, transportation, online services, and international communications. It helps unify scheduling across regions within the United States and Canada and is frequently adopted as a reference point in global meetings, digital platforms, and cross-border operations. Its widespread recognition ensures clear and consistent time coordination across diverse sectors and geographies.
